Relationships between categorical fields

The most common technique for describing categorical data is to create a summary table or graph indicating the number and percentage of cases falling into each category of a variable. In this section, we will discuss two nodes, the Distribution and Matrix nodes, that allow us to investigate the distribution of and relationships between categorical variables.

Distribution node

The Distribution node allows you to visually assess the distribution of a categorical field so that you can see the frequency and percentage of each category. This node also allows you to see the relationship between two categorical fields. Let's go through an example of how to use the Distribution node:

1. Open the Relationship stream.
2. Place a Distribution node from the Graphs palette onto the canvas.
3. Connect the Type node to the Distribution node.
4. Edit the Distribution node.

To see the distribution of a categorical field, place a field in the Field drop-down list:
